About Stackyard — Card Offer Stacker
One of our clients spent about two years doing this math in a spreadsheet. One day he walked us
through it and we couldn't believe nobody had fixed it yet.
Here's the problem. When you buy through a buying group, your profit isn't one number. It's the
group's commission, plus whatever card offer you happen to have sitting there, plus whatever a
cashback portal is paying that week. Three numbers, three different websites, and the deal might
be gone by the time you've added them up.
So we built Stackyard.
It reads the offers and deals that are already on your screen while you're logged into your own
accounts, and it just tells you the answer:
$30 profit per item. Pay with Capital One. Go through BeFrugal.
WHAT IT PULLS TOGETHER
Your card offers from the major issuers, with more added as we validate them.
Live deals from the buying groups you already use.
Live cashback rates from the portals you'd normally check by hand.
It badges your toolbar the moment something profitable shows up, and it can ping your phone
through Discord so you don't miss it while you're out. There's also a My Stats tab where you can
log what you've actually bought and keep a running total of what it's made or cost you.
ABOUT THOSE BELOW RETAIL DEALS
If you're in this world you already know that eating $12 to put $599 on a card is sometimes the
entire point. Stackyard doesn't pretend those are losses. It shows you what it costs, what
percentage of your spend that is, and what it works out to per point.
And if you tell it you're chasing a $4,000 minimum spend, it works out the cheapest set of deals
that gets you there. Every so often it finds a path that actually pays you to finish your bonus,
which is a good day.
WHAT IT WILL NEVER ASK FOR
Your passwords. You sign into your accounts the same way you always have, on their own websites.
Stackyard only reads what's already on the page.
There's no server behind this thing. Nothing gets sent anywhere. It all lives in your own browser,
and if you uninstall it, it's gone. The only thing that ever leaves your machine is a Discord
alert you set up yourself, going to your own channel.
We're OneLonelyCow. We run a reshipping service for people who do this, which is how we ended up
building it in the first place. If something's broken or wrong, tell us and we'll fix it.
